Pin Function
Positive Supply to lower gate drivers. Decouple this pin to VSS (Pin 7). Bootstrap diode
connected to HB (pin 2).
High-Side Bootstrap supply. External bootstrap capacitor is required. Connect positive side of
bootstrap capacitor to this pin. Bootstrap diode is on-chip.
High-Side Output. Connect to gate of High-Side power MOSFET.
High-Side Source connection. Connect to source of High-Side power MOSFET. Connect
negative side of bootstrap capacitor to this pin.
High-Side input.
Low-Side input.
Chip negative supply, generally will be ground.
Low-Side Output. Connect to gate of Low-Side power MOSFET.
